Olivia Munn had double mastectomy for breast cancer

Munn said she took a genetic test in February 2023 that checks for 90 different cancer genes and was negative for all. Even so, her doctor decided to calculate her Breast Cancer Risk Assessment Score and that "saved my life," Munn wrote.

Recording a high score, Munn had imaging tests and then got a biopsy, which found she had an aggressive form of cancer in both breasts. She had a double mastectomy 30 days after the biopsy and has had four surgeries in the past 10 months. She said she kept it private because: "I needed to catch my breath and get through some of the hardest parts before sharing."

Munn thanked family and friends, especially her partner, comedian John Mulaney, "for being there before I went into each surgery and being there when I woke up, always placing framed photos of our little boy Malcolm so it would be the first thing I saw when I opened my eyes."

Munn was a correspondent on The Daily Show with Jon Stewart and her movie credits include Magic Mike, The Predator, Office Christmas Party and X-Men: Apocalypse.
